Magradze also stabbed two male employees who tried to intervene, police said. The employees' injuries were not life-threatening.

Magradze also tried to stab a police officer who tried to take him into custody, police spokeswoman Stephanie Slater said.

Magradze's brother, Alexandre Magradze, 29, also was taken into custody.

Gill died from his injuries at Delray Medical Center, police said.

Saturday, a woman who answered the phone at the home of Gill's relatives said: "They want privacy at this time."

James Hall, the owner of The Backyard, said Gill was a regular patron who was known to be a "gentle giant."

He said it appeared Gill may not have been directly involved in the altercation at first and seemed to be trying to protect another patron.

"We think that we built a really great clientele. It's the kind of clientele you dream of for what this place was," Hall said. "This unfortunate, tragic incident kind of sets back what we're trying to accomplish here. Our hearts and prayers go to the family of the victim."

The bar opened about a year ago in the Heart of Boynton, a part of the city that has long strived for redevelopment.

The Magradze brothers were transported to Bethesda Memorial to treat minor injuries, but both now are in Palm Beach County jail, Slater said.

Vakhtang Magradze was charged with second-degree murder, aggravated assault on a law enforcement officer, resisting an officer with violence and two counts of aggravated battery. Alexandre Magradze was charged with disorderly conduct.
